Hello,
I want to simulate a laser welding process with the active cooling. When I checked the publications like "A new distributed cooling method for mitigating residual stress in friction stir welding", "Efficacy of active cooling for controlling residual stresses in friction stir welds", I found that some researchers used FILM user subroutine to model the active cooling device. You can find my subroutine as attached. However, I want to apply this active cooling device in my FEM model with the nozzle which will be active and moving along my weld section. In the experiments, I also want to put a active cooling device next to the laser which will spray liquid Ar to cool the weldment faster. Does anyone know how I can implement moving active cooling device in the FILM subroutine or is there any other option to simulate active cooling in DS Abaqus with FORTRAN.
Many thanks,
Mete
